Detailed Product Description

PVC Waterproof Membrane

It is a composite increased, the plastic material is a polymer, high-density waterproof material, with a unique antioxidant, anti-ultraviolet performance, the physical and chemical indicators have reached the national standard, high-performance polymer waterproof material.

The main raw material is PVC resin, by adding all kinds of special additives and anti-aging ingredients. Using high-grade production equipment and advanced technology .products have great tensile strength, high elongation, shrinkage of small, low-temperature flexibility, and long service life.

PVC rosin as main raw materials, added with various kinds of specific assistant and ageing resistance agents, it adopts high-grade equipment and advanced technological process. Those products are of great tensile strength,high strenthing rate,good suppleness in low temperature,long service life,ect.

Product performance stable, quality reliable, convenient construction. It can be widely applied to high-end roofing construction, underground engineering waterproof, waterproof top surface of the tunnel, of leaking garbage dump, swimming pools, subway and so on.

Product performance :

1.Long service life, anti-ageing, roofing materials can be used for more than 20 years, the underground up to 50 years.

2. Tensile strength, high elongation, heat treatment of small size changes.

3. Good low temperature and good adaption to temperature changes in the environment.  

4. Penetration is good, green roofs can be made.

5. Good anti-perforation

6. Facilitate the construction, when welding, solid reliable and environmentally-friendly non-polluting.

7. Chemical corrosion resistant, and suit for special occasions

8. Good plasticity, convenient and quick corner detail treatment.

9. Easy maintenance and low cost

Execution process introduction

PVC waterproof coiled material has three execution methods as machine fixation, affix fixation, press and covering fixation

For example: Mechanical fixation of the construction process

1 Laying non-woven fabrics.( adopt when specific requirements in engineering)

Base treated, lay non-woven fabric and special gaskets and nails fixed.

2 pave and fix up waterproof coilded material

Pop-up standard lines, tthen pave the waterproofing membrane by line, using hand-held torch to solder waterproofing membrane on the dedicated pads.

3 Welding waterproof coilded material

The coilded material could be welded by hot air or hot wedge. Welding procedures shall be in accordance with pre-air temperature, humidity, humidity, and the surfacehumidity of  membrane . Regulate the welding temperature, humidity, pressure and do welding test.

4 inspect&measure welding line

Seal the end of the airway,insert  gas needle into  two-seam airway,press to a certain pressure, and stop within 15 minutes after the pressure drop inwhich is not more than 10% ,that's qualified.
